MILK Annnron.

Application med october 7, 1925. serial nt. 61net.

tating milk so as to thoroughly aerate the' same for vthe purpose of removing from the milk the animal heat'therein.v

Another very important 'object of the invention is to provide a machine of this nature which is exceedingly simple in its construction consisting merelyv ofy a casing .housing ap spring motor, and having extended therefrom a driven shaft which may be engaged with a propellershaft.

Another important object of the invention is to provide a device of this nature which may be supported on the upper edge of a bucket or like container while the'propeller or agitator is in operation.

A still further very important object of the invention is to provide a device of this nature which is inexpensive to manufacture, easily manipulated, light, compact, strong, durable, efficient, reliable, not likely to easily become out of order, and otherwise well adapted to the purpose. for which-'it is designed.

With the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in f' the combination and arrangement of parts -as will. beN hereinafter more fully described and claimed.

In the drawing AFigure 1 is aside elevation ofthe machine emiodying the features of my invention, an 1 Figure 2 is a top plan view thereof. Referring to the drawing in detail, it will be seen that 5 designates a casing having mounted therein a conventional form of spring motor 6 which is operatively associated with a driven shaft 7 extending through the bottom vof the casing and terminating at its outer end in an eye or loop8. The springfmotor 6 is windable by means of key 9. On the top of the motor housing or casing 5, there is pivoted a4 plurality of bars 10 which may lhe swung to extend outwardly beyond the peripheryof the casing as is shown in Figure 2 in order that the casing may be supported inside the bucket very easily-out of order.

while the bars are engaged to extend over the edge thereof.y A- propeller shaft 11 is provided atone endwith a hook`12 engageable with the eye 8. A propeller 13 is mounted at the other end of the/propeller shaft 11, and functions as an agitator. The propeller 13 has its blades pitched so as to tend to draw the milk upwardly from the bottom of thc buck t as is indicated by the arrows 111. and the shaft l1 is adapted to rotate in'thedirection indicated by the arrow 15, and consequently the propeller shaft 11 is Amaintained in axial alignment with the shaft 7.

It is thought that the construction, operation, vand advantages of theinvention will now be clearly 4understood without a more detailed description thereof. It isdesired to point out that the shaft 11 is easily and quickly detachable from the shaft 7 so that the shaft 11 and propeller 13 may be thoroughly cleaned. rlhus the device is highly sanitary. The device also possesses an exceedingly simple construction and consequently'can be manufactured at a very low cost, yet the device is very strong and durable and has no likelihood of becoming The structure is exceedingly compact and is capable of being readily supported in a bucket in the proper manner for allowing the shaft 11 to depend down into the bucket so that the agitaing propeller 13 may operated proper y.

. The present embodiment of the invention has been disclosed merely by way of example since in actualv practice it attains the features of advantage enumerated as' desirable in the statement ofthe invention and the above description. It will be apparent that numerous changes in the details of construction, and in the Icombination and arrangement of parts may be resorted to without departing from the spirit or scope yof the the invention,

in the casing, 'a shafty operatively associ- 'ated with the prime mover `andextending from the casing and terminating exteriorly of the casing in an eye, a shaft terminating in a hook engageable with said eye, an agltating unit on said second shaft including a pair of blades having a pitch so that the rotation of the irst shaft causes the agitating unit to tend to rota-te in a liquid to pull the second shaft from the first shaft thereby tending to maintain the second shaft in alinement with 'the rst shaft, and a plutalner.

In testimony whereof I aiiix my Signature.

BENNETT OLSON.
